I have received mail from income tax regarding high transaction on saving account interest. (1) Instantly I logged into complaince portal and found that yes I need to pay the amount, I said yes there 2) on 1-apr, i paid the same extra amount to the tax dept. 3) Now what should I do , is there any action on me because the ITR which i submitted in DEC doesn't have this amount which I paid on 01-Apr-2021 (challan). Pls guide
